+**WARNING from 2018-10-21!** It appears that the cache and log directories
+of dnscrypt-proxy don't sometimes get created automatically (at least on
+Debian GNU/Linux 9.6 (stretch).
+
+If this happens to you or you would like to be sure to get them:
+
+```
+sudo mkdir -p /var/cache/dnscrypt-proxy/ /var/log/dnscrypt-proxy/
+sudo chown -R _dnscrypt-proxy:nogroup /var/cache/dnscrypt-proxy /var/log/dnscrypt-proxy
